Muscle Sensing Device Design Using a PANDA Ring Resonator System

Abstract

We propose a micro-optical sensing system for muscle contraction and movement measurement, in which a PANDA ring resonator type is used as a basic optical device called Muscle Optical Sensor (MOS) system. The MOS system consists of an optical add/drop filter which is connected to two micro-ring resonators, of which the right ring is a sensing unit and the left ring is a reference ring. The key contribution of this paper is a novel approach for measuring contraction and transfiguration of muscles by using the small scale optical device. The contraction or transfiguration of muscle is directly perturbed into the sensing unit, which changes the optical path length. These resultant changes in wavelength (∆λ) are measured and obtained by the difference of the sensing and reference signals. The experiment was conducted by using the MATLAB and Opti-wave programs, which indicated that the changes in the sensing radius were associated with the change in wavelength. The results and techniques can be used beneficially for muscle sensing applications. 

Facial Gesture Measurement Using Optical Muscle Sensing System

“…Recently, Yupapin and Sarapat have shown the advanced optical sensing system that uses the whispering gallery modes (WGMs) of light within a micro-scale modified add-drop filter circuit for various sensing applications [26]. In our previous research [27][28] we developed a conceptual framework and device model of a muscle measurement system using optical devices which measure muscle contractions. As well, the results from our previous research can be used for pattern recognition.…”
